Class 11PhysicsWork, Energy, Power and CollisionWork Energy Theorem and Conservation of Mechanical Energy
DifficultCorrect the following sentence: 'System cannot possess mechanical energy but possesses work.'
(N/A) The correct statement is: '$A$ system can possess mechanical energy but cannot possess work.'
Reasoning:
$1$. Energy is a state function,meaning it is a property of the system's state. Therefore,a system can possess internal energy or mechanical energy.
$2$. Work is a path function,not a state function. It represents energy in transit across the boundary of a system due to a force acting through a distance. $A$ system does not 'have' or 'possess' work; it performs work or has work done on it.

View Solution$A$ particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of the particle. The motion of the particle takes place in a plane. It follows that:
$A$ force acts on a $3 \,g$ particle in such a way that the position of the particle as a function of time is given by $x = 3t - 4t^2 + t^3$,where $x$ is in metres and $t$ is in seconds. The work done during the first $4 \,s$ is ..... $mJ$.

View Solution$A$ bus moving on a level road with a velocity $v$ can be stopped at a distance of $x$ by the application of a retarding force $F$. The load on the bus is increased by $25\%$ by boarding the passengers. Now,if the bus is moving with the same speed and if the same retarding force is applied,the distance travelled by the bus before it stops is
